The last eruptive activity of Mount St Helens was in July of 2008.
The eruption of Mount St. Helens in 1980 released an estimated energy equivalent of 24 megatons of TNT, which is approximately equivalent to 1,600 Hiroshima bombs.
The eruption of Mount St. Helens in 1980 was triggered by a combination of magma rising towards the surface, increasing pressure in the volcano, and a sudden release of built-up gases. This led to a flank collapse on the north side of the volcano, resulting in a massive eruption that devastated the surrounding area.
The eruption of Mount St. Helens in 1980 was relatively short, lasting for about nine hours. However, the effects of the eruption, including the eruption column and pyroclastic flows, had long-lasting impacts on the surrounding area.
Very violent. The last big eruption flattened trees and anything else for miles. It looked like a bomb exploded.
I think it was in 1796 though I'm not sure :)

There have been no reported deaths resulting from an eruption of Mount Aso in recent years. The mountain has had sporadic eruptions, with the last major eruption occurring in 2016, but there were no casualties reported.

Mammoth Mountain, located in California, has not erupted in recorded history. It is considered to be a dormant volcano, with its last known eruption dated back to roughly 57,000 years ago. It is currently being monitored for any signs of potential volcanic activity.
The last eruption of Mount Pelée in Martinique was in 1932.
